A vascular graft includes a flexible substrate that can assume an unrolled configuration, in which the substrate extends along a main extension plane, and a rolled-up configuration, in which a first side of the substrate is facing radially inward and a second side of the substrate is facing radially outward. At least one pressure sensing device is arranged on the first side of the substrate and includes a first electrode, a second electrode, and a piezoelectric element arranged between the two electrodes. At least one velocity sensing device is arranged on the first side of the substrate and a first electrode, a second electrode, and a piezoelectric element arranged between the electrodes. The graft can be used in a vascular graft system.

The present disclosure provides systems, methods, and computer-readable storage media having functionality to prove immutability of blockchains without accessing user data. A user may submit data for storage to a data management server and the data management server may generate one or more data records corresponding to the data at a database and one or more blocks at a blockchain, each block corresponding to of the data records. Block information associated with the generated blocks may be transmitted to a remote computing device for storage at a database. Prior to storing the block information, the remote computing device may sign the data using a private key or other cryptographic technique. To validate a block, raw block information may be retrieved from the blockchain and compared to the signed block information. If the signed block information matches the raw block information, the block may be determined to be valid (e.g., unchanged).
